I have only picked a couple of ripe tomatoes so far, but the vines are all full of green fruit. This variety I grew from seed that I bought from Park Seed. They are called "Costoluto Genovese", an Italian heirloom tomato that is supposed have an intense flavor that makes them good for canning and sauce. I love the lobed shapes on these!
I planted many different varieties, and in the first planting I had a nice chart of which were where. But after they all froze to death and I had to scurry to replant, I didn't track placement. So until they ripen, it is hard to tell which is which. These Genovese ones are unmistakeable though.
